 Description

The energy received from that sun as well as the demand of hot water are magnitudes that depend on the time and they will not always coincide perfectly.

 

Knowing this, if you want to maximize the daylight hours, it will be necessary to accumulate energy at the time of day when this is possible and use it when there is demand.

 

The solar accumulators, are responsible for storing the heat produced by the thermal solar panels. They are virtually insulated devices, which release very little heat, provided that the sam is maintained with the absence of consumption and/or solar radiation. In renewable energy systems where the heat source is intermittent, such thermal storage equipment is indispensable. It stores the energy as sensible heat by way of water that will later be consumed.

 

The dimension of the thermal storage accumulators should be proportional to the estimated consumption and should meet the demand for hot water of one or two days. It is important to determine the proper relationship between the surface area needed to catch the sun’s rays (catchment area) and volume of accumulation adequate enough for our application because large catchment areas with relatively small volumes lead to higher temperatures of storage (and more work) therefore reducing the efficiency of the collectors.

 

In the accumulator, water tends to stratify by temperature due to the density of the same as a function of temperature. Thus, the temperature at the top of the reservoir will be higher than the bottom. It is important to enhance this effect using upright bins with height at least twice the diameter.

 

 

The heat transfer fluid passes through the heat exchanger located at the bottom of the tank (cold area) and transfers heat to the water inside the accumulator. Once transferred the heat transfer fluid returns to the collectors where they repeat the heating process, so the performance of the installation will be facilitated by working at temperatures as low as possible. Drinking water is always taken from the upper reservoir.

 

  • Stable thermal stratification by way of a slender tank in the shape of a column and a steady flow at the entrance of cold water and hot water outlet.

  • Thermal insulation made of rigid polyurethane 50 mm thick.

  • Optimum solar load through its coils with a large exchange capacity to improve the efficiency of the accumulator by the solar energy input.

  • Prepared for the incorporation of electrical resistance heating thermostat as a subsidiary system.

  • All hydraulic components needed to connect the solar collector and boiler support are incorporated.

  • Upper and lower pods for the insertion of PT1000 temperature probes for temperature control.

  • Use of organic materials made high strength and quality.
